Deuteronomy 7:21-23

Amplified Bible

²¹ You shall not dread them, for the Lord your God is in your midst, a great and awesome God. ²² The Lord your God will clear away these nations before you little by little; you will not be able to put an end to them quickly, for [if you did] the ^[a]wild animals would become too numerous for you. ²³ But the Lord your God will hand them over to you, and will confuse them with a great panic until they are destroyed.
